This paper describes an application of statically indeterminate fracture mechanics, SIFM, to evaluating the structural integrity of axially cracked internally pressurized and spinning cylinders. The following points were made clear : The J-integral obtained from SIFM agrees well with the conventional fully plastic solution given by Kumar et al. in the case of the internally pressurized cylinder ; SIFM can give the J-integral value equivalent to the J-integral keeping path independence in the case of the spinning cylinder : Based on these results, a quantitative study was carried out for the United Kingdom Atomic Energy Authority, UKAEA, test : here, a structural integrity test was performed under pressurized thermal shock (PTS) by using the spinning cylinder.
